摘要： A bicycle includes a conventional pedal crank and chain drive together with a conventional derailleur shifting mechanism operative to selectively transfer the drive chain between alternative rear sprockets of the bicycle drive system. A chain ring is rotatable in response to pedal crank rotation to transfer pedal crank power to the rear sprockets. A pair of guide blocks define respective internal guide channels through which the drive chain passes toward and from engagement with the chain ring. The guide blocks are maintained at their respective positions by a guide support plate secured to the bicycle frame.

摘要： A device for preventing derailment of a bicycle chain of a bicycle. Upper and lower guide members are positioned strategic to a drive sprocket of the bicycle to guide and maintain the chain in engagement with the drive sprocket regardless of the tension of the chain. The upper and lower guides force the chain to be engaged a longer circumferential distance on the drive sprocket to prevent the chain from jumping off the drive sprocket. Circular guards are mounted on each side of the drive sprocket to protect the drive sprocket and the chain entrained thereon from impact. The spacing of the circular guards provides a channel for receiving the chain as it traverses the drive sprocket.

摘要： An assembly for minimizing the disengagement of a chain from a chain ring is disclosed. The assembly includes an inboard leg and an outboard leg. The outboard leg is configured to slide vertically relative to the inboard leg. A fastener passes through the inboard leg and outboard leg and defines the upper and lower limit of sliding of the outboard leg.

摘要： A device for retaining a bicycle chain on a sprocket includes a base plate defining a plurality of fastener openings centered on an origin. A center of each of the plurality of fastener openings is disposed at a first radial distance from the origin. The origin defines an axis extending substantially orthogonally from a plane defined by two lines extending from the origin and at least two centers of the centers of the plurality of fastener openings. A first guard is secured to the base plate and includes a first guard retaining surface including a first curved surface defined by a second radial distance from the axis that is greater than the first radial distance and a first guard guiding surface having a first end adjacent the first guard retaining surface and a second end distal from the first end. The first end is disposed at the second radial distance from the axis. The second end is disposed at a third radial distance from the axis. The third radial distance is greater than the second radial distance. A second guard is secured to the base plate and includes a second guard retaining surface including a second curved surface defined by the second radial distance from the axis. A second guard guiding surface has a first end adjacent the second guard retaining surface and a second end distal from the first end. The first end is disposed at the second radial distance from the axis. The second end is disposed at a fourth radial distance from the axis. The fourth radial distance is greater than the second radial distance.

摘要： The disclosure describes an electromechanical rear derailleur for coaxial mounting on a rear wheel axis. The rear derailleur has a base member, a pivot mechanism, a movable member having a chain guiding arrangement, and an electromechanical drive for driving the pivot mechanism. The pivot mechanism connects the base member to the movable member. The chain guiding arrangement is connected to the movable member for rotation about an axis of rotation. The base member comprises a first connection end, which can be mounted coaxially with the rear wheel axis, and a second connection end for coupling with the pivot mechanism.

摘要： A chain guide for a bicycle having may include a base frame and a height adjustment member connected to the base frame and slidable relative to the base frame and lockable in a first position by engaging a first locking member. A retaining member may be pivotally connected to the height adjustment member and may be pivotable about a pivot axis a retaining position, in which the retaining member is positioned to obstruct lateral movement of the chain away from the chainring thereby preventing lateral misalignment between the chain and the chainring, and a removal position, in which the retaining member does not obstruct lateral movement of the chain away from the base frame while the height adjustment member is locked in the first position. The pivot axis may be spaced apart from the first locking member.
